You needed to assert on employer. Unions do help and can help in such matters.
Unions in your state have traditionaly been strong.
One Presdpective: Escalate (as per internal matrix) to good offices of appointing authority, MD, CEO to exhaust the internal options and make them a party.
Other Prespective: You have waited enough. Your counsel may opine that you can approach CGIT than going in for conciliation. (If you are covered by the def. of Workman).
Appropriate Govt. in your case is Central and not state. (Don’t err).
In one case/thread at LCI the querist (Unit Manager) that was supported by us posted that he approached CGIT and he succeeded.
Other Prespective: As per schedules mentioned in the Acts for compensation posted for you, your designation might be covered. Employer could have informed the Commissioner as in the Act and police. The links that I have sent to you are sufficient to indicate what/how much compnesation you can get.
